    If you read the Collins restoration article
    [​IMG]
    Rebuilding the Collins 516F-2 Power Supply by Jim Garland, W8ZR
    http://www.w8zr.net/vintage/tcvrs/516F2 Rebuild.htm

    you may have noted that Jim used silver-ceramic terminal strips that he salvaged from old Tektronix oscilloscopes.

    He used several to build and mount the two diode rectifier banks as well as to hold the new capacitors and voltage equalizing resistors.

    If you use these strips it's important to use solder that has a small amount of silver alloyed into it (which Tektronics did) to prevent the process from lifting the silver coating off the ceramic. My old RadShack paper catalog showed it as part numbers 64-013 and 64-035.

    Correct.
    Many older Tek scopes had a small loop of silver alloy solder inside for that specific purpose.

    You can also use Kester Pocket PaksĀ® exclusively available through NTE Electronics dealers.
    These are usually $ 2 to $ 3 USD per pocket tube

    ERV:

    Collins used those types of strips in the 75A-1 receiver and Heath used them in the TX-1 Apache.
